Which tool is used to create a CANES user manually?

The correct choice is Active Directory Users and Computers (ADUC) because this tool is specifically designed for managing user accounts in a network environment. ADUC allows administrators to create, delete, and manage user accounts, including setting permissions and organizing users into groups. When manually creating a CANES user, this tool provides the necessary functionalities to enter user details, assign user roles, and configure access rights in accordance with organizational policies.

The other options do not serve the function of user account management within a directory service context. Microsoft Outlook is primarily used for email and calendar management rather than user account setup. Windows Terminal is a command-line interface that interacts with various shell environments but does not have the built-in capabilities for user management. System Configuration, typically used for managing system settings and configurations, also does not encompass user account creation functionalities found in ADUC.
